Help with stuffed endive appetizer ideas please

I'm planning on serving stuffed endive as an appetizer for a cocktail party. What should I stuff them with? In the past I've done a curried chicken salad and a smoked salmon salad. I'd like to do something different. Ideas?

I'm also thinking of serving something atop cucumber rounds other than a smoked salmon type of thing. Ideas appreciated for this as well.

I have stuffed endive with goat cheese, topped with candied pecans and then drizzled honey over the top. It was very delicious and popular. As far as topping the cucumber rounds, I have topped them with chopped black olives and feta cheese for a mediterranean flavor.

I like endive with a walnut salad. Trim endive leaves and separate leaves. Prepare the dressing by mashing a small garlic clove to a paste with 1/2 teaspoon salt. Whisk the garlic paste with 2 tablespoons each fresh lemon juice and EVOO, and 1 tablespoon mayonnaise. Cut a one-quarter pound piece Parmesan into 1/8"dice. Finely chop celery to make 1/2 cup. Stir the Parmesan and celery into the dressing. All this preparation can be done up to one day ahead.

When you're ready so serve, stir into the dressing 1 cup of walnuts that have have been lightly toasted and finely chopped, and 1/4 cup of finely chopped Italian parsley leaves. Spoon about a tablespoon of salad onto the stem end of each endive leaf and arrange them on a plate.

The quantities for this salad will fill the leaves of about 4 Belgian endives.
